R-AL.SR
Mechanical seal Alfa Laval R-AL.SR - single, unbalanced, does not depend on the direction of shaft rotation. The design is characterized by a small working length and the presence of a sinusoidal spring (Sinusoidal Wave - Springs). Suitable for working with viscous liquids, and with appropriate friction pairs - and with abrasive ones.
Application: most often in rotary vane (cam) pumps, Alfa Laval SSR series SRU1, SRU2, SRU3, SRU4, SRU5, SRU6, as well as SSP® pumps SR, NMOG series. The R-AL.SR seal has proven itself in pumps for the food, brewing, dairy, and sugar industries.
Type: Roten 7K Seal, Aesseal W03U/W03SU/W03S/W03DU/W03, Vulcan 1688W, Roplan RTH87/R90 seal, John Crane 87 (EI/EC) seal, Sterling 280W/282 seal.
